WINDOWSI-IADE-WINDING- MECHANISM;

Specification of Letters Patent.

Patented Oct. 7, 1919.

Original application filed October 2, 1916, Serial No. 123,436. Divided and this application filed March 12,

To all whom it may concern Be it known that I, LoUIs B; GIRARD, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles, State of California, have invented a new and useful WindowShade-Winding Mechanism, of which the following is a specification.

This invention relates to means for winding up shades on their rollers after they have been mounted thereon, this application be ing a division of my application for window shade mounter, filed Oct. 2, 1916, Ser. No. 123,436.

The main object of this invention is to provide a machine whereby the Winding of the shade upon the roller may be effected conveniently and rapidly.

Another object of the invention is to provide a machine of this kind in which the shade winding means is in operation only when actually winding a shade upon its roller, being adapted to be easily thrown out of operation when the winding'is completed.

A further object of the invention is to provide means for lifting the roller clear ofthe supporting table, to enable winding of the shade thereon, and to automatically control the operation of the winding means by such lifting movement, so that the winding means is brought into operation as the roller is raised.

Another object of the invention is to provide means whereby the same machine may be utilized for winding shades upon rollers of different lengths.

Another object of the invention is to pro vide means whereby rollers of diiferent sizes may be accurately centered on the winding means so that the shade is wound smoothly and evenly on the roller.

The accompanying drawings illustrate a machine embodying my invention and referring thereto:

Figure 1 is a plan view of the machine and a portion of the table with a roller and shade in position thereon.

Fig. 2 is a section on line 2-2 in Fig. 1, with the roller removed.

Fig. 3 is a section on line 3 3 in Fig. 1.

Fig. 4 is an end view of the machine, taken from the left end of Fig. 1.

5 is a cal sect on o t chuck f r rotating the roller.

Serial No. 154,163;

Fig. 6 is a vertical section of for the roller.

The shade roller support, winding mechanism, and operating motor therefor are preferably mounted on a table 1 as shown. The shade roller support 2 may be formed of channel iron with the flanges 2 thereof the pick-up extending. upwardly so as to form guards for the roller 20 and retain it in proper position,

as indicated in Fig. 8, and may be fastened ating arm or handle 10'projecting from a sleeve 11, which is mounted on the shaft by a key or spline 12 engaging in a longitudinal groove 13, so as to be slidable thereon but to cause shaft 5 to turn with handle 10.

Sleeve 11 is further provided with an arm 14 extending rearwardly and having at its rear end a pick-up or roller engaging device 15 adapted to rest normally on roller support 2, and formed preferably as a head on a spindle 16 mounted to turn in a bearing 17 on arm 14, said head having a conical socket or recess 18 adapted to receive the pin at one end of the shade roller 20.

A driving chuck 22 is provided for engaging the other end of the roller, said chuck turn in bearings 24 and 24 on a chuck carrier as to turn therewith. The pickup shaft 5 with thepick up arm 14: and chuck carrier 25 carried thereby, constitute a pick up means mounted to swing vertically on the bearings 9, so as to raise the pick up arm and the chuck, together with the clutch device connected thereto, simultaneously, and thereby lift the shade roller bodily from the supporting bed and, clear the latter sufliciently to enable winding of the shade on the roll without interference by the bed. A rubber friction ring 22 is secured in chuck 22 to engage the end 0f the shade roller and cause being mounted on a mandrel 23, mounted to a '25, which is mounted on pick-up shaft 5 so it to turn with said chuck. Said friction ring is provided with a recess 40, whlch is somewhat larger'than the shade roller pin and has a conical p0rti0n41 at'its inner end, formed in the mandrel 23, the purpose of which will appear hereinafter. Bearing 24 is preferably provided with an end thrust ball bearing 26 for the chuck 22. A pulley 27 is fastened to mandrel 23 by set screw 39 scrwing in the hub portion of pulley 27, and said pulley is provided with a groove 27 for receiving'a round belt 28, which passes over a pulley 30 on the shaft 31 of a motor 32, which may be an electric motor, belt 28 being loose and therefore inoperative when the parts are in normal position. Pulley 30 is preferably provided with wide flanges 30 to retain the belt thereon when slack. A guard 33, isprovided for pulley 27, being formed. for example as a half ring flange on a crossarm 34 having a hub 34" adjustably mounted on an extension 35 of bearing 24,

by means of a set screw 36.

A shade supporting platform 45 is provided on table 1, inclining upwardly and forwardly to near the level of the top of the shade roller when in position on the roller support 2, and adapted to hold the shade in 7 position to be wound up on the roller.

The operation is as follows:

The shade roller 20 is placed upon the roller support 2, with the pin at one end inserted in the recess 40 of chuck 22 and the shade cloth is drawn froma pile of shade cloths 4:6 in position on platform 45 and fastened to the roller in any suitable manner, for example by hand, using a hammer and'tacks, or as set forth in my application Ser. No. 123,436, of which this application is a division. Recess 410 being larger than the pin at the end of the roller permits the pins of different size rollers to enter the same while the roller lies fiat on the roller support soas to give a solid support for the operation of fastening the shade to the roller.

When this has been completed, the handle 10 is moved to the left on pick-up shaft 5, so as to cause pickup device 15 to engage one end of the shade roller, the pin at this end of the roller entering recess 18, which is 1 conical in shape to receive pins of different size rollers and to center them accurately in the pick-up device during the winding operation.- The operator holdsthe roller to the left by a slight pressure upon handle 10, which causes the roller to be gripped between pick-up 15 and chuck 22, and then operates handle 10 so as to turn pick-up shaft 5 and raise chuck 22 and pick-up -15. This lifts the shade roller off the support 2 and at the same time causes the pulley 27 to engage belt 28 so as to tighten said belt on said pulley'and on pulley 30, which is operated by I 1 motor32, and cause it to rotate pulley 27 and the chuck 22 connected thereto. The

shade roller is thereby rotated so as to wind theshade thereon, the operator exerting a slight pressure to the left on handle 10 with one hand to hold the shade tightly against the friction ring 22 on chuck22, and pressing the shade with the other hand to cause it to wind tightly on the roller. The conical 22 and pick-up 15, together with the shade and roller, onto support 2, and loosening belt 28 to such an extent that it is no longer able .to turn pulley 27, which may therefore be said to be automatically thrown out of operation, when the Shade'is completely wound. The operator moves handle 10 to the right so as to remove pick-up 15 from the end of the shade roller, and the shade roller with the machine, which is then ready to receiveanother roller. What I claim is:

shade wound thereon is removed from the I 1. In a shade winder, a table provided with means for supportinga shade -roller, a

' horizontal shaft mounted to swing vertically on said table, a clutch support mounted on said shaft to turn therewith, aclutch mandrel mounted to turn in said clutch support,

3. In a shade winder, a shade roller support and means for picking up the roller therefrom comprising a horizontal shaft, a clutch support carried thereby, a clutch rotatably mounted on said clutch support, a pickup device mounted to slide on said shaft and to turn therewith, and provided with a handle for operation thereof to bring the pick-up device against one end of the shade roller lying on its support, so as togrip the roller between the pick up device and the clutch and to then raise the pick up device and the clutch simultaneously by rotation of the shaft, and means for driving said clutch.

4. A shade winder constructed according to claim 3, provided with driving means brought into cooperative relation with said clutch to drive the same when the said clutch is raised by operation of said handle.

5. In a shade winder, a roller supporting bed, a shaft extending parallel to said bed, and a pick-up device mounted to slide along said shaft and to turn thereon, said pick up device having means for engaging one end of a shade roller and having a handlefor moving it along said shaft to bring it into engagement with one end of the roller and for turning it on said shaft to lift the roller from said bed.

6. A shade winder comprising a supporting bed for a shade roller, a table provided with means for supporting a shade in position for winding 011 said roller, means for rotating said roller to wind the shade there on and means for lifting said roller bodily from said bed during the winding operation, to prevent interference of such bed with the winding of the shade on the roller.
